Answer:

1. Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle.

2. The drop in progesterone levels causes the lining of the uterus to fall away.

3. Your body discards the monthly buildup of the lining of your uterus (womb). 

4. Menstrual flow might occur every 21 to 35 days and last two to seven days. 

5. Menstrual cycles tend to shorten and become more regular as you age.
